    Abstract: PROBLEM TO BE SOLVED: To provide an MOS technology power device having integrated circuit in which the series resistance of gate can be decreased without increasing the number of gate metal finger parts. SOLUTION: The MOS technology power device of integrated structure comprises a plurality of functional units of basic component formed in a lightly doped first conductivity type semiconductor layer 1 wherein the functional unit has a second conductivity type channel region 6 coated with a conductive insulation gate layer 8 including a polysilicon layer 5. The conductive insulation gate layer 8 has resistivity significantly lower than that of the polysilicon layer 5 superposed by a highly conductive layer 9. Since a resistance introduced by the polysilicon layer 5 is shunted by a resistance introduced by the highly conductive layer 9, total resistivity of the conductive insulation gate layer 8 is decreased.

    Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of an integrated edge structure for a high voltage semiconductor device. SOLUTION: A first conductivity-type (n-type) first semiconductor layer 41 is formed, and a first mask is formed on the upper face. A part of the mask is removed, and at least one opening is formed in the mask. Second conductivity- type impurities are introduced into the first semiconductor layer 41 through an opening, the first mask is completely removed and an N-type second semiconductor layer 42 is formed on the first semiconductor layer. The impurities implanted into the first semiconductor layer are diffused, and a P-type doped region 220 is formed in the first and second semiconductor layers. Final edge structure provided with plural N-type overlap semiconductor layers 41-46, and two inserted columns in plural overlap semiconductor layers formed of the overlap of plural P-type doped regions 220-260 implanted from the opening is formed by repeating six processes once or more. The column near the high- voltage semiconductor device is deeper than the column far from the device.

    Abstract: PURPOSE: To reduce the manufacturing process of the channel region of a basic function unit and to reduce the ON resistance of a power device by forming the deep body part and the channel part of a body region only by ion implantation without performing any thermal diffusion treatment. CONSTITUTION: After a first dopant is selectively ion-implanted into a heavily doped part 5 in a direction that orthogonally crosses a semiconductor surface with a proper amount of dosage and an energy of ion implantation with an insulation gate layer 8 as a mask, a second dopant is selectively ion-implanted into a region 6 along a direction that is inclined at a prescribed angle in an orthogonally crossed direction, thus forming a body region 2. Then, a large dosage of third dopant is ion-implanted into the greatly doped part 5 to form a source region 7 that is nearly aligned to the edge part of the insulation gate layer 8, thus reducing the manufacturing process of the channel region of a basic function unit since no thermal diffusion treatment is made and reducing the on resistance of a power device.
